Ssh-2.0-cisco-1.25 Vulnerability _top_ ✦ Quick

The string SSH-2.0-Cisco-1.25 is not a vulnerability itself, but rather the SSH banner (software version identifier) typically broadcast by Cisco IOS and IOS XE devices during the initial connection phase.

Many Cisco devices using the Cisco-1.25 SSH stack were found to be vulnerable to the Terrapin attack. ssh-2.0-cisco-1.25 vulnerability

devices. While the banner itself is not a vulnerability, it helps attackers identify the underlying software to target specific known flaws. Cisco Community The string SSH-2

1. Upgrade to a patched version: Upgrade to a Cisco IOS or IOS XE version that is not vulnerable to this exploit.
2. Disable SSH: Disable SSH on the device if it is not required.
3. Implement additional security measures: Implement additional security measures, such as access control lists (ACLs) and intrusion prevention systems (IPS), to detect and prevent exploitation attempts.

The string SSH-2.0-Cisco-1.25 is a software version banner identifying the Secure Shell (SSH) server implementation used by a wide variety of Cisco products, including Catalyst switches ISR routers ASA firewalls Upgrade to a patched version : Upgrade to

Phase 4: Continuous Monitoring

• Deploy SNMP traps for SSH login failures.
• Use NetFlow to detect anomalous SSH connection attempts.
• Re-scan quarterly with credentialed vulnerability scans (not just banner grabs).
